Its up to you. I do not know what you have now. I do not know your expertise. I do not know what are are afraid of losing. I started using Linux in 1998 and from then until around 2007 I never used the proprietary graphic drivers. I did NOT want to risk my desktop being messed up.
My financial situation changed around then, and I had more than one PC, and hence had a backup, so I became a bit more adventurous and started using proprietary drivers and I was AMAZED at how easy it was (doing things like what I described above). But by then I had 8 years Linux experience.
Of course I probably could have done the above immediately when I first started using Linux, but I am incredibly conservative, and it was NOT important to me at the time (in 1998), and I had things that WERE important that I did not want to risk losing, and I had little time then to debug/experiment.
This is your call.
I think it is easy.
I think I outlined the steps adequately.
But I have no idea as to your assessment.
Sorry, I can’t answer your question.
